Steel Spoke Specification Example for Assembly Programmes: Off-Road Version

This is a worked specification for steel spoke in a off-road version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The off-road version version exists because the duty cycle on assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — ABS Plastic, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • anodising
  • sintering
  • shot blasting
  • cold forging
  • injection moulding
  • surface grinding

Where this example applies

Programmes that run off-road version most often specify this build for assembly programmes. Related applications include aftermarket retail, municipal fleets, off-road bikes, camper conversions, fleet maintenance.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 4.0 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SGS-compliant build instead of a fresh interpretation.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

What testing is included?

Standard lots ship with dimensional and hardness reports. SGS documentation is issued with the shipment when your market requires it.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
